Hydroelectric Generating Stations

(as at January 1st, 2018)

A hydroelectric generating station is a plant that produces electric power by using water to propel the turbines, which, in turn, drive the alternators.

These power stations generate about a quarter of all the electricity used in the world. With access to vast water reserves, Hydro-Québec uses water to generate almost all of its energy output. In this way, the company helps reduce greenhouse gas emissions.

The installed capacity of Rocher-de-Grand-Mère generating station is the maximum allowed under the operating permit.

The head of water shown corresponds to the largest value (greatest height), if there are several values. The head varies with each generating unit. Refurbishment work may therefore change the water head value.

Year of commissioning of first and last generating unit in each facility.

McCormick generating station is operated by a limited partnership between Hydro-Québec (60%) and Alcoa (40%).

Generating station not connected to the Hydro-Québec grid and operated by Hydro-Québec Distribution.
